Thisinvention relatesfto a closure device of the cap type and intended for-closing a bottle, jar or the'like containerfhaving a rim o'rfexternal shoulder around its mouth. 1

The invention has fOIfObjeOt'tO provide a closure which, after it ha's been aflixe'd in position and. removed'therefrom, cannot be replaced without showingthat it'hasbeen removed, and is inexpensive to manufacture and reliable in use. 5 Other objects of theinvention are to provide a closure which consists oftwo parts connectedtogether, viz. a metal embracing bandfand' lid of penetrable material suchas cardboard, and also toprovide a quickly disconnectible means between saidband and said lid. A. further object is to provide a twoepart closure which can-be inturned or wheeled below the rim of the container: mouth "The? invention is. hereafter. described with reference'to the accompanying drawings; Figure l.is a'iplan View ofthe'closure ready so I as to secure. the

Figure 8 is a plan of a further modification.

disc, is shown at a; This lidais shown in Figure l engaged an embracing band of metal I) having separated ends. The band I) in this example is of such a length that its ends do not meet around the mouth of'the container 9 but face one another with a small gap -0 between. The band I) is provided with a flange at at top and at bottom 7 the band depends below the widest portion of the bead orrim it upon the container 9. This dependent portion is shown in Figure 2 By pulling th "FREDERICK. eus'rnvonsfemziinn', on.

A tongue 6 provided upon the central'portion of the band at one end of said bandand not provided with the flange d, overlaps the '55 1 i gap *0 and the other endof the band 5; The flangedoverlapstheperiphery of the lid a r and it is" provided with inwardly directed serrations or claws f-w'hich'are downturned to bitevinto the periphery of the lid a. These v claws are preterablyarranged in sets along or aroundtheflange'd,four such sets'being shown in the drawings (Figures 1 and l);v

Further itis advantageous tolocatefoneof I said sets ofclaws withone half the set near each ofthe adjacent ends of the fianged an'd close to the gap 0. In'other vvordajoneof the four sets is divided on eachsideof gap 0', asclearly seen in-Figure. a

If desired,- a gasket 2' of the lusua'l kind mouth see Figure 2. v

The metal band I) and thelidw are secured the container mouth. The-closure so formed withthe serrations-or claws f biting into the v. maybemounted on .top of the container:

lid m is held down upon thelmouth of the bottle ,or container with the band bembrad ing the rim orfbead h' upon the exteriorof c the container mouth and the lower edge or skirt'b oftheband b is then wheeled;orfinturnedv below the external r'imfor' bead h,

which operation secures the closureihfposi I 'tion 5;Th is wheeling operation isfwell 'knownn connection with closure; devices more fully.-, q p V h h h e tongue a away from the disc a; the claws f'upon' that endof the band 7) will be torn'from the' material of the disc a ;(see Figure 14) and themetallband b will consequently, ior a portion ofzits length, be

disengaged 'from the rim h. This H opening out of theflembracijng band 2) allows the clos ure-"to, be-removed from the mouth ofthe container. :The lid a shows where the claws have been torn out, sothat it provides evidence of-tjhe' closure having. been removed.

Itwill be-fnoted, first, that the discg orlid jaiholds the, 'metal band in the closed or and it is thoughtunnec'essar'y it'o describeit encircling position by means of theserra tions' 7, secondly, that the Wheeling oi the 1 lower edgeof the band I) holds that member in the known manner under the rim h of the container, and thirdly, that the material of V the disc a yields and gives way when a pull takes place on' the overlapping tongues and it'is deslred to remove the closure.

By reason of the tearing of the claws from the lid a' and fthe '2 consequent marks upon the periphery of the lid 0 near the tongue 6, the closureiwillclearly show that it has been removed. v r

In Figure 7,. the separated ends ot as band b over l ap one another by means of a step j in the length or the band, the tongue 6 being a continuation of the overlapping part of the band 6., Y
